This makes it clear which context the returned SD is allocated on, as
a number of callers do not want it on talloc_tos().
As the ACL transformation allocates and then no longer needs a great
deal of memory, a talloc_stackframe() call is used to contain the
memory that is not returned further up the stack.

When setting an ACL without any of the user/group/other entries, ZFS
automatically creates them. This can at times confuse users a lot. This
parameter denies setting such an acl, users explicitly have to for example set
an ACE with everyone allowing nothing. Users need to be educated about this,
but this helps avoid a lot of confusion.

in fset_nt_acl().
Need to watch the build farm to make sure I haven't broken the AIX or Solaris ACL modules.

this can only be done via fset_nt_acl() using an open
file/directory handle. I'd like to do the same with
get_nt_acl() but am concerned about efficiency
problems with "hide unreadable/hide unwritable" when
doing a directory listing (this would mean opening
every file in the dir on list).
Moving closer to rationalizing the ACL model and
maybe moving the POSIX calls into a posix_acl VFS
module rather than having them as first class citizens
of the VFS.

Up to now, get_nt_acl() took a files_struct pointer (fsp) and
a file name. All the underlying functions should need and now
do need (after the previous preparatory work), is a connection_struct
and a file name. The connection_struct is already there in the
vfs_handle passed to the vfs functions. So the files_struct
argument can be eliminated.
This eliminates the need of calling open_file_stat in a couple
of places to produce the fsp needed.

This is the next step in preparation of a get_nt_acl prototype change.

There was one caller of smb_get_nt_acl_nfs4() forgotten
in the change of return value.

bugs in various places whilst doing this (places that assumed
BOOL == int). I also need to fix the Samba4 pidl generation
(next checkin).

This adds the two functions talloc_stackframe() and talloc_tos().
* When a new talloc stackframe is allocated with talloc_stackframe(), then
* the TALLOC_CTX returned with talloc_tos() is reset to that new
* frame. Whenever that stack frame is TALLOC_FREE()'ed, then the reverse
* happens: The previous talloc_tos() is restored.
*
* This API is designed to be robust in the sense that if someone forgets to
* TALLOC_FREE() a stackframe, then the next outer one correctly cleans up and
* resets the talloc_tos().
The original motivation for this patch was to get rid of the
sid_string_static & friends buffers. Explicitly passing talloc context
everywhere clutters code too much for my taste, so an implicit
talloc_tos() is introduced here. Many of these static buffers are
replaced by a single static pointer.
The intended use would thus be that low-level functions can rather
freely push stuff to talloc_tos, the upper layers clean up by freeing
the stackframe. The more of these stackframes are used and correctly
freed the more exact the memory cleanup happens.
This patch removes the main_loop_talloc_ctx, tmp_talloc_ctx and
lp_talloc_ctx (did I forget any?)
So, never do a
tmp_ctx = talloc_init("foo");
anymore, instead, use
tmp_ctx = talloc_stackframe()
:-)

return to correctly return NT_STATUS_INVALID_OWNER if it
should be disallowed. Matches better what W2K3R3 does.
NFSv4 ACL module owners, please examine these changes.
